Genes affected

LRRC8E (HGNC:26272): (leucine rich repeat containing 8 VRAC subunit E) This gene encodes a member of a small, conserved family of proteins with similar structure, including a string of extracellular leucine-rich repeats. A related protein was shown to be involved in B-cell development. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

Collection Method:clinical testing

The c.21C>G (p.F7L) alteration is located in exon 2 (coding exon 1) of the LRRC8E gene. This alteration results from a C to G substitution at nucleotide position 21, causing the phenylalanine (F) at amino acid position 7 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
